UNITED STATES WESLEY J. RI-IEINFRANK, OF CHICAGO, ILLINOIS.

TOY TURBINE.

Application filed November 6, 1924.

To all vi /tom it may cow-0cm:

Be it known that I, lVnsLnr J. RHEIN FRANK, a citizen ot' the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful linprovemcnts in Toy Turbines, of which the following is a full, clear, concise, and exact description. ri-iference being had to the accompanying drawing. :lorming a part of this specification.

My invention relates to toy turbines and it has particular reference to that class of toys which altord not only pleasure but also serve to improve the mind of the child by reason of their practical alue from the standpoint of educational activity. This invention consists oil. means for providing the child with an opportunity to observe the operation ot' a toy turbine and give consideration thereto, thereby presenting a variety of purposeful, educational, practical and usetul objects which the outwardly observahle tacts gleaned from the mere mechanical toys in common use never accord to the child.

(hie ot the objects oil my present invention is to provide a toy which is simple in its construction, easily and readily assembled and inexpensive to manufacture.

Another object of my invention is to provide a toy which in additionto being pleasing; entertainment for a child is useful and helpful from an educational standpoint.

Another object of my invention is to provide a toy turbine which will take a ,predominant part in the play ol the child in that, by reason of the power derived from my toy turbine, thechild is able to propel and operate his other mechanical toys.

Another object of my inventionis to provide water buckets tor a rotorwheel in a toy turbine which are integrally formed upon the rotor and which, by reason of such construction, possess durability and reli ability. 7

Further objects of myinvention will appear from the detailed description of my invention and the appended claims.

By reason of my invention, I may provide the child with a toy which is inexpensive and safe to operate. The toy of my invention is capable of performing in the same manner as an electric motor and functions quite as satisfactorily. My present in serial No. 748,010.

transmits power in much the same manner as an electric motor, that is, by means of a belt which may be easily and rapidly attached to a driving pulley with which I have provided my toy turliiine. 7

Further, I utilize a method in constructin r my toy turbine thatobviates the necesy of frequent inspection of the inner-construction of my toy. I form the water buckets integrally with the rotor, thus making them permanently attached thereto and incapable ot being jarred loose, removed or otherwise loosened or detached.

For a better understanding oi? my invention reference may be had to the accompanying! drawing in which Figure 1 is a side elevational view ot a toy turbine embodying one :form of any invention, with the lower portion on? the turbine casing broken away;

Fig. 2 is a cross-sectional view oi my toy turbine taken onthe line 22 of Fig. 1:

Fig. 3 is a view showing a sheet metal section constituting the rotor immediately prior to its being formed and bentto provide water buckets; and

Fig. l is a view-otthe same portion, with two completed buckets and i one bucket to be bent and formed as the others.

A casing 1 encloses a rotor wheel l to which buckets Qare I attached. The buckets are adapted to receive the water stream directed upon the toy turbine thereby revolving; and propelling the rotor wheel 4. The casing l is supported upon legs 6 which are all'ixed to a base 7. The casing El. comp an rapper portion. 1 and a lower portion 1" and is made water tight by securing these two portions together through the medium of flanges 16. vent pipe 12, having openings at 13 enters the lower portion 1' of the casing and below the vent pipe :12, -a nozzle 10 likewise enters this casing. At 11 the nozzle 16) may be attached to a rubberhose or other suitable means for conducting Water to the nozzle 10 from :a water ttaucet. At the lowest portion of the casing is an exhaust pipe 9 with its opening at 8 which serves to remove the deenergized water from the casing 1. A shaft 14 is secured to the rotor wheel 4 and attached thereto by means of attaching and supporting members 15. The shaft 1 L is rotatably mounted upon bearings 17 and, at one end of the shaft 14, a driving pulley 3 is attached.

Referring now to the construction of the a .ises

rotor wheel 4 and its buckets 2, said rotor wheel 4 is stamped in circular form. from a piece of sheet metal.

In Figs. 3 and a I have illustrated the method of forming the rotor b ckets 2. The sheet metal circular form is radially slotted at spaced points as shown by slots 18 and 20. Circumferential slots 19 are formed which are spaced a short distance from the outer periphery of the rotor. The slots 19 are bisected by the radial slots 18 and the radial slots 20 and are spaced from one another substantially as shown. The sheet metal is then bent upwardly along the lines 43 and 25 adjacent respectively to the slots 18 and 20. It will be noted that the lines .43 and 25 are discontinued where they intersect the circumferential slots 19. These portions constitute the two sides of the rotor bucket 2. The metal between the slots 18 and 20 is then bent circumferentially along the line 24 which is intersected at each of its ends by the adjacent slots 19. This portion of the metal constitutes the lip of the bucket. The portions 26 and 27 of the metal that are adjacent to the outer periphery of the rotor are bent back as shown in Fig. ti and serve as reenforcing means for the lip 2st of the bucket. The portions 26 and 27 may, if desired, be welded or soldered to the corresponding side portions of the bucket. hen the bucket assumes the shape as shown by the bucket 2 of Fig. 4 it is then twisted so that the plane of the bucket is perpendicular to the plane of the rotor as shown by the buckets 2 and 2 of Fig. i. From the foregoing it is to be noted that the buckets are integrally formed upon the rotor 4 and through a very simple manipulation of the sheet metal constituting; the rotor.

Vi hile I have shown and described one embodiment of my invention it is to be understood that many modifications can be made therein without departing from the spirit and scope of: the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the U. S. is:

1. A toy turbine comprising a rotor, and buckets therefor, said rotor being stamped from a piece of sheet metal in the form of a circle which is radially slotted and circumferentially-slotted at the tip of the buckets for the purpose of bending and tormingsaid slotted portions into said rotor buckets, the

metal adjacent to said circumferential slots being; bent to form sides and lips for the rotor buckets.

2. A toy turbine comprising a rotor formed from acircular metal sheet that is radially and circun'iterentially slotted atspaced points adjacent to the periphery, the metal adjacent to the radial slots being: bent upwardly to constitute the sides of the rotor bucket and the metal intermediate the radial siots and adjacent the circumferential slots being bent upwardly to form the lip of the rotor buckets, and the metal between the bent portions then being bent in aplane perpendicular to the plane of the rotor thereby forming a rotor bucket.

3. A one piece rotor comprising a plurality of peripherally disposed scoop-shaped buckets having their planes coaxially and perpendicularly arranged, said buckets being formed at spaced radial slots and spaced intercepting circumferential slots in a sheet metal disk.

l. A one piece rotor comprising a plurality of peripherally disposed scoop-shaped buckets having; their planes coaxially' arranged, said buckets being formed by circumi'erentially and radially slotting a disk member at spaced points, the sides of the buckets being formed at said radial slots and being intercepted by the circumferential slots and the lips of the buckets coinciding with said circumferential slots.

5. A one piece rotor comprising a plurality of peripherally disposed scoop-shaped buckets having their planes coa-Xially arranged, said buckets being formed by circumferentially and radially slotting a disk member at spaced intervals and bending and I twisting said slotted segments so that the planes thereof are perpendicular to the circumference or" said disk member.

6. A one piece rotor comprising a plural ity of peripherally disposed scoop-shaped buckets having their planes coaXially arranged, said. buckets being formed by stamping spaced circumferential slots adj acent the periphery of a disk member, and by stamping radial slots which bis-ect each of said spaced circumferential slots and bending such slotted portions of said disk member into substantially scoop-shaped members.

In witness whereof, I have hereunto subscribed my name.
